Most storage devices in this range also lack the support options that enterprise servers do.

This sentence is the third italicized block of text seems odd.

Fixed, thanks.

thanks, fixed.

@LAH3385 might be good to start a thread and try to determine what your needs are before going down the path of technology. By the time you were asking this question, you were already in pretty deep assuming certain products, product categories and platform HA. We should start with a business needs analysis, use that to set goals and then use the goals to select technology approaches.

Here is an example:

Three hosts, each running two Windows Server VMs, each with two sockets. Say Dell Power Edge R610 or HP Proliant DL360 nodes. Windows Standard Licensing.

Cost per license: ~$700

To license each node to run its normal load is $700 for a total of $2,100.

If we want to address the ability of any node to be a failover for the others or for non-disruptive maintenance, we need an additional license per machine. So we suddenly jump from $700 per node to $1,400 per node and the whole cluster jumps to $4,200 while gaining nothing during normal production times.

Now that only addresses single node failover. If we want to maintain the ability to do failover during times of maintenance we need yet another license for each machine! That means $2,100 per machine and $6,300 for the cluster.

Suddenly $350 per virtual machine in licensing has exploded to $1,050. A non-trivial increase.

Now we can choose which level and which features we want, but typically the value of an inverted pyramid is sold based on this top level of flexibility. If we are dealing with Data Center licensing this is more obvious and far less complex, but SMBs would rarely pay for that level of workload and may not think through the additional costs that this style of architecture potentially bring to the table.

Peer-reviewed my behind… This post represents a complete and total spew of utter garbage. Really??? Emotional reactions to “the problem”?? “An IPOD”?? Even suggesting (though not “our best option” dumping all your brand new equipment and moving to a single host?? Please focus on removing your introspective nears and pathetic sarcasm to a minimum. You couldn’t smell the manure stink more had you forcefully shoved your head inside an elephants rear end…. Do the world of Actual IT Professionals a favor and take your biased disinformation to a place where no-one else can be poorly and deceitfully guided by it.
Sincerely,

Emotional reactions such as this guys whole post... nothing but emotion, zero rationale.

It sounds like someone wasted a million dollars of company money and is trying discredit reality.

It's called "reverse rationalization" in psychology context. Humans want to believe that we are rational, logical creatures. But most of our decisions are emotionally based and made faster than we can rationalize them. Then, when our decisions are questioned, we go back and our brains try to remember there being logic that we used to make the decision. If there is logic, we recall that logic. When there isn't logic, our brain freaks out and either constructs false logic to make it seem rational, but that often makes it seem even more crazy to outsiders looking at us spouting gibberish. And if our own brains realize the gibberish or this is pointed out, it can actually trigger the fight or flight response when all logic shuts down and we just panic.

Might be suggesting a 3rd party review of the solution so look out for an E-mail NTG 😄

@Minion-Queen waits with baited breath.
